Software Radar: New Reality

New conception of software radar (SR) providing high degree of programmable ability is described. The SR architecture is tailored to efficient execution of all traditional radar-algorithm with maximum flexibility. History of SR design during the last twenty years analyzed and accompanied by bibliography. Great achievements in SR implementation became after appearance of high performance DSP and FPGA. Attention devoted to methodology of software algorithms verification using half real simulation. Two goal has been achieved: analytical approach gave new calculated results of algorithm efficiency and checked software implementation of the new algorithm using simulation
